웃음을 이용한 다중음성치료기법(SKMVTT<SUP>®</SUP>)이 성대용종 환자의 음성개선에 미치는 효과

김성태(Seong-Tae Kim),정옥란(Ok-Ran Jeong),안철민(Cheol Min Ahn) 한국음성학회 2008 음성과학 Vol.15 No.2

Vocal polyp is one of the representative chronic diseases of vocal folds, and it can be cured by voice therapy and/or laryngeal microsurgery. However, the existing therapeutic methods about vocal polyp are in great demand. The purpose of this study was to evaluate the effect of vocal improvement between laryngeal microsurgery and SKMVTT<SUP>®</SUP>(Seong-Tae Kim's Multiple Voice Therapy Technique), which was designed by the author. We identified 37 patients, who were diagnosed with unilateral vocal polyp, aged from 21 to 62 years(mean age: 46 years). 21 patients were treated by the SKMVTT<SUP>®</SUP> and the other 16 patients were only treated by the laryngeal microsurgery. All patients who were treated by the SKMVTT<SUP>®</SUP>, received 12 sessions of treatment, and were evaluated before therapy and after finishing the 12th session. The patients who were treated by laryngeal microsurgery, were evaluated prior to and at least 8 weeks after surgery. The results showed that the SKMVTT<SUP>®</SUP> produced better results compared to the laryngeal microsurgery alone. The SKMVTT<SUP>®</SUP> produced better results, especially, at the initial stage of voice therapy compared with those of laryngeal microsurgery. In this study, we can suggest that SKMVTT<SUP>®</SUP> may be useful in improving the voice qualities of vocal polyp patients. However, more data should be collected and evaluated to be widely used in other clinics.

본 연구에서는 ICT 교유그의 효과를 높이고자 ICT 활용 학습 과정 시 학습자에게서 나타나는 오류의 사례들을 분석하여 오류 유형을 설정하고 그에 대한 효과적인 처치 방안을 탐색하였다. 관찰, 면담, 설문 조사 등의 방법을 이용하여 오류 사례를 탐색한 결과 기능 혼동 오류, 개념 혼동 오류, 인터페이스 해석 장애 오류, 심리적 불안으로 인한 오류, 학습자 성격 유형에 의한 오류, 습관적인 오류 등 6가지 오류 유형을 설정하였다. 그중 가장 많은 빈도를 차지하는 기능 혼동 오류와 개념 혼동 오류 중심으로 웹 기반 Q&A 학습 시스템을 개발하고 이용한 오류 처치 방안을 제안하였다. 또한 제안한 오류 처치 방안을 현장에 적용하고 그 효과를 검증하였다. In this paper, I analyze error cases a learner made during learning using ICT, set up error types, and search for effective treatment methods in order to enhance the effects of ICT education. I search for error case to use the methodology of the study which is observation, interviews, and survey. I set up the error types which is the error type of confusion with functions, that of confusion with concepts, that of barriers in interface interpretation, that caused by psychological anxiety, that according to learner personality patterns, and habitual error type. The biggest frequency of errors was found in the error type of confusion with function and that of confusion with concepts, whose treatment methods were searched for using the web-based Q&A learning. Also, I apply the error treatment methods on the classroom and prove the effect.

초,중등 학생의 정보통신 윤리 실태 분석

안성훈 한국컴퓨터교육학회 2004 컴퓨터교육학회 논문지 Vol.7 No.1

국가 정보화 정책이 중점 추진되면서 1990년대 중반 이후 정보통신 이용자수가 급격히 증가하고 있으며, 10대 청소년 계층의 90%이상은 일상생활에서 정보통신을 이용하고 있는 것으로 나타났다. 정보통신 이용의 급격한 증가는 우리 사회를 의사소통이 신속하고 편리한 커뮤니케이션의 장으로 변모시켜 사회 각 분야의 생산성과 효율성을 높여주고 있다. 그러나 그에 따른 각종 역기능도 심각하게 나타나고 있어 사회 문제로 대두되고 있다. 특히 10대 청소년 계층이 그 역기능에 가장 심각하게 노출되어 있는 것으로 나타나 대책마련이 시급하다. 따라서 본 연구에서는 초 ? 중등학교에서 실시되고 있는 정보통신 윤리교육의 현황을 파악해 보고 학생들의 정보통신 이용 실태와 비교 ? 분석함으로써 보다 현실적이고 효과적인 정보통신 윤리교육의 방향을 탐색하고자 한다. The number of people using the information communication have being rapidly increased owing to promote a national information policy. The rate of teenager using the information communication are over 90 percent. We can communicate quickly and easily owing to the rapid increment of the information communication. But there are adverse effects because of the rapid increment of the information communication. Specially, teenagers have been quickly influenced by the adverse effects. We must consider a counterplan for the adverse effects. Therefore, in this paper, I will survey the present status of ethics education for information communication which have been taught in school and the actual condition using information communication of teenagers. And I will analyze the connection of them. In addition, I will propose the desirable direction of ethics education for information communication.

恨의 맺힘구조와 力動的 想像力 : <招魂>과 <배따라기>를 중심으로 centered the work of「Chohon」and「Baettaragi」

안성수 제주대학교 1988 논문집 Vol.27 No.1

Summary The purpose of this study was to investigate the chain generative structure of wail and "Han" (a kind of particular korean emotion) in relation to the process of figuration in literary works. For this aim. the writer proposed establishment of concept about lamentation, wail and"Han" since in dealing with the problem concerning "Han" 1amentation and wail as preceding stage of "Han" are generated. The writer defined lamentation as crying which accepts sorrowful situation given asresigned situation, while wail was defmed as an extreme crying which denies that situationand rather has will power and action of overcoming the situation. Therefore, lamentation itself has difficulty m switching over to the smouldering structureof "Han".On the contrary to lamentation, wail that denies the given situation and has wil1of overcollling and transcendence is sublimated to the structure of "Han". The structure of 「Chohon」 and 「Baettaragi」 exammed m this paper uses the amplifying devices of special emotion for the purpose of remforcing tone of wail. This amplifying devices help the smouldering structure to transfer to the solution structure by using thepower of wail roused. The device of rhythln m「Chohon」 and the double frame m「Baettaragi」 function as the amplifier for it· 「Chohon」 is staying on the stage forsearching ways to so1ve the smouldering of "Han". whereas 「Baettaragi」 vents its "Han" through the pattern of wandering throughout character's life. However, these two works can be classified into the type of the slnouldering structureof "Han". As mentioned above, "Han" is fundalnentally a kind of tragic ernㅇ tion originatedfroln the interaction between subject and object and it has three generative structure: byself, by others and by interaction between self and others. 「Chohon」 and 「Baettaragi」,thus, can be called the story of "Han" in the sense that the subject influences the objectand the for ther who will receive that influence again from the latter bears "Han" inhis(her) inner world. Another pomt the writer proposed is on the dynamic principle that transforrns thesrnouldering structure of "Han" into solution structure of it. There are severa1 methodsand process to so1ve "Han": dialectical, sequentia1 prmciples and so on. Because "Han"has an organic and cornplex generative structure, the researcher must consider variety manalyzing the structure of "Han", in「Chohon」 and 「Baettaragi」 the writer explained dynarnics in relation to the dialectical imagination that sublited extreme emotion into "Han".

안용희,장성호,안종수,박출재,김수생 동아대학교 공과대학 부설 한국자원개발연구소 1994 硏究報告 Vol.18 No.2

This study has been carried out to determine the toxicity of agricultural chemical (TPN) as to wastewater treatment. This system used Aerated Submerged Up-Flow Biofilm Reactor. This reactor can withstand the variation of concentration, flow rate and presence of certain toxic materials in the wastewater to be treated. An acclimation experiment was variated influent COD from 250㎎/ℓ~70㎎/ℓ. The agricultural chemical was added to obtained optimum condition at influent COD 400㎎/ℓ by the acclimation experiment. The conclusions from the experimental results are as follows ; 1. Influent COD concentration was variated 250㎎/ℓ~600㎎/ℓ. The treatment efficiency was stability(86% to 93.3%). When influent COD was 400㎎/ℓ, the treatment efficiency was at best-93.2%. Accordingly, this system was proved to be suitable in treating the wastewater with wide range of concentration. 2. The influent TPN concentration below 1ppm at Up-Flow Aerated Biofillm Reactor, raised no harmful result to treatment efficiency. 3. The treatment efficiency was decreased to 29.8% when the lapse of time. 4. When the experimental TPN toxicity was compared with the DDT toxicity in the reference, it was proved that both of the toxicity had the similer trend.

企業의 輸出行動에 관한 硏究

安世遠,余聖遇 慶星大學校 1991 論文集 Vol.12 No.3

This issue is designed to present some of the recent thinking and empirical evidence on the subject of "internationalization" The term "internationalization" is used here to refer to " the process of increasing involvement in international operations" and also to highlight the variety in firms' international market entry and development modes. Companies' international involvement can best be described as evolutionary. A fundamental proposition of many writers on internationalization is that a firm's export behavior is a developmental process involving a sequential step wise progression. Thus the more international experience the company has, the lower the perceived risk of running a foreign business. On the other hand, some researchers also postulate that internationlization is a sequential process and formulated a stages model. The process by which a firm demonstrates exporting behavior is usually conceived as evolving through various states, though the suggested number and characteristics of relevant stages vary. A review of the major studies suggests four groups of factors as likely determinants of whether firms engage in export marketing. The factors can be identified as 1) management expectation and the strength of managerial aspirations for various business goals 2)the level of organizational commitment to export marketing 3) attention-evoking factors 4)export barriers It is generally recognized that the expansion of a nation's exports has positive effects on the growth of the economy as a whole as well as on individual firms. An overall objective in most countries is to find ways to increase exports. Increase exports may be achived either by stimulating exporting firms to export more or by inducing non-exporters to start exporting . Despite the potential contributions of a higher export level, many firms appear not to be fully maximizing their potential gains from international trade. An important objective of this study, therefore, is to profile these firms at different levels of international development and to identify determinants of export marketing behavior. Futher, because the determinants differ from one export stage to another, the relative importance are also analyzed. Another major objective is to suggest a theoretical insight which could be used by public or private export promotion agencies for estimating the export potential of firms. No comprehensive or widely accepted theory of the process by which firms expand and develop their international business activities has yet emerged. However, there does appear to be some concensus emerging concerning certain general characteristics of this process. 1) It is an incremental learning process which takes place over time as the firm gradually increases its involvement and commitment in foreign markets. 2) This process could be identified several development stages according to degree to involement in foreign operations. 3) Factors that influence firm's progressions from one stage to the next tend to differ by stage. 4)Differences of export potential in both exporting and nonexporting firms can be explained by various aspects. The issue begins with export as an expansion alterantives for the company, in chapter III, a review of existing theretical and empirial studies on the export behaviour of firms . A chapter IV of this study tries development of conceptual integrated export behaviour of firms. Lastly conclusion and future research directions are present in chapter V.

刈取管理가 Pearl Millet[Pennisetum typhoideum]의 刈取後 新枝의 發生, 乾物重 및 枯死에 미치는 影響

安桂洙,趙聖均 順天大學校 1984 論文集 Vol.3 No.1

This experiment was carried out to investigate the effects of the different cutting stage and cutting height on the appearance, dry weight and the death of new bud (branch and tiller) of pearl millet (Pennisetum typhoideum). The cultivar used in the present study was feed mill. The experiment was undertaken in the Experimental Livestock Farm of Suncheon National College, 1984. The results obtained are summarized as follows: 1. The frequency of the branching was increased and the rate of the tillering was decreased as the high stubble height, both of the frequency of the branching and the rate of the tillering were also decreased as the late cutting stage. 2. The yield of forage mostly depended on the tiller regardless of cutting height, and minor portion of the yield was resulted from the branch. 3. In the number of dead bud, there was no significant difference in different cutting stage, and was increased as the low stubble height.

웨이브릿 변환 이용 디지털 영상 데이터 워터마킹

안성수,이준 동신대학교 2004 論文集 Vol.14 No.-

정보통신의 비약적인 발전에 힘입어 멀티미디어 데이터는 언제 어디서든 전송 받거나 공유할 수 있게 되었다. 아날로그 형태에서 디지털의 아날로그를 형태로 빠르게 대체되고 있으며, 디지털로 신호를 표현하는 방법은 기존 사용하여 표현하는 방법에 비해 많은 장점을 가지고 있다. 하지만 디지털로 된 데이터는 언제 어디서든 대단위 복제가 가능하다. 즉, 저작권 침해, 불법 복제 및 배포, 손쉽게 위조할 수 있다는 점이 그것이다. 디지털 영상 정보의 보호를 위해 디지털 영상의 불법적인 내용 조작을 막고, 영상의 소유권을 보장할 수 있는 방법으로 디지털 워터마크(Digital Watermark)가 있다. 디지털 워터마크는 공개키 알고리즘이나 방화벽 등으로 해독된 영상에 대하여 부가적인 보호를 제공한다. 디지털 영상에 대한 저작권 정보, 배포자 정보 그리고 사용자 정보를 영상에 삽입함으로써 훗날 법적인 문제가 발생하였을 때 해결책을 제시할 수 있다. 본 논문에서는 디지털 영상 데이터의 정보 보호를 위해 주파수 영역에서의 웨이브릿변환(Wavelet Transform)을 이용한 이미지 적응 디지털 워터마킹(Image-Adaptive Digital Watermarking) 방법을 제안한다. 이미지 적응 웨이브릿(Image-Adaptive Wavelet)은 영상을 주파수적으로 분해하면서 각 대역들의 공간 영역에서의 정보를 함께 지니고 JND's(Just noticeable difference)을 포함한다. 이미지 적응 웨이브릿의 이러한 특성을 이용하여 다해상도 분해하고, 손실 압축(Loss Compression)이나 필터링(Filtering), 잡음(Noise)등에 크게 영향받는 저주파 성분과 인간의 시각적으로 큰 의미를 갖는 고주파 성분의 특성을 이용하여 워터마크를 삽입한다. Multispectral image is wavelet trans formed and classified into one of three classes considering reference characteristics of the subband with the lowest resolution. Then, for a reference channel which has the highest correlation with other channels, the variable VQ is performed in the classified in the classified intra-channel to remove spatial redundancy. For other channels the CIP is performed to remove spectral redundancy. Recently, aegis of authentication and creator's copyright has become a matter of great concern by the diffusion of multimedia technique and the growth of the internet and the easily duplicated property of digital data. Consequently, many active researches have been made to protect copyright and to assure integrity by inserting watermark into the digital data. In this paper, watermark is repeated through the entire image and adapted to the content of the image.
